Perhaps. I want something 100% compatible to Raspberry Pi (so it would support "hats" designed for the original Raspberry PI and also sun the original Raspberry PI OS, not the x86 clone) but way more powerful (for the reasons I mentioned - browsing the "modern" websites like YouTube without tears + networking). And no, mini-ITX won't fit in the place I need to put it.

Yeah, I find I am the opposite in that I don't want the Pi 4, think the Pi 3 is sort of the sweet spot for performance/price.

Pi Zero's have such wonky connectors....
